How crucial is an exhaust fan and a carbon filter?
I cant find anything in my country as a kit, but would buying them piece by piece work? Example something like in the photo connected to an air duct and then to a carbon filter? Or if the exhaust fan is not crucial? how can i get rid of the smell in a cheaper way?

2x2 Circulating Fan
What is the best circulating fan for a 2x2 tent available on the european market? I bought a Secret Jardin MO20 oscillating fan, and I highly regret it because I have read several reviews mentioning that it can catch fire. Is there any other good alternative for circulating air?

Smell through filter exhaust
The smell inside is quite strong and is coming through the filtered exhaust. Is this normal, or does it mean I need to replace my filter soon?

Maintaining VPD
I've got my photoperiod doing well in a 2x2 tent. I'm trying to regulate my VPD with what I have on hand. Currently I'm running my exhaust fan for 8 minutes every hour to get an average VPD around 1, but I'm concerned about the swings. Am I micromanaging?

Brauche ich unbedingt einen (Schwenk-) Lüfter in meiner Growbox?
Habt ihr schon mal ohne (Schwenk-) Ventilator in der Growbox angebaut? Wenn ja, welche Erfahrung habt ihr dabei gemacht? Ich möchte nur ungern einen Ventilator einsetzen, weil das vermutlich die Lautstärke der Box deutlich erhöht. Schon mal vielen Dank für eure Erfahrungen.

Is this clawing, or just droop, (pots fairly dry)And why can’t I get RH below 70% with more than adequate ventilation, I’m recalibrating my hygrometer in the meantime.

Are (constantly) high daytime temperatures a huge problem in flower?
My day temperature since turing my light up to max during flower are reaching 29-30c | 84.2 - 86f, while the daytime RH is at roughly 40% - 50%. Is the high temperature something to be concerned about? pics 1 and 2 are the exact same data as pics 3 and 4, just set to c/f each.

Ventilation set up
I just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?

Whataretheeeeeese
The soil holds too much the water and takes too long to dry up, no fan or temps will drop bellow acceptable, so besides taking advantage of the sun whatelse to do? They seem to hold well and have steady grow even without watering for 5 days... they dont need oxigen or what?

I’m thinking of putting a 12” fan up high to move the air to one space and an extractor to take out the air and a second cooler as I got up to 30c on a day of 15c so need some measures! Question is will it work? Don’t want to waste time on pointless things!

What’s up guys me again😂 I’ve got my hps up and running and I’ve got the temperature under control by having my fan blowing directly at the light and I’ve added a oscillating tower fan. How can I keep the temps up when lights go off? Many thanks!

Won't Oscillate Anymore
I was wondering what type of oscillating fans that everyone uses in small grow tents. I have been using the Vivosun fans and since they won't last I'm looking for alternatives. In case it matters I'm growing in a 27x27x63 MarsHydro tent.
